What is the approximate concentration of A3− ions in a 1.0 M aqueous solution of H3A? Assume that H3A has the following ionization constants at 25°C: Ka1 = 1x10−4, Ka2 = 1x10−5, Ka3 = 1.0x10−6 (A) 1x10−3 M (B) 1x10−6 M (C) 1x10−8 M (D) 1x10−9 M (E) 1x10−11 M

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

the answer is c. nacl
